heres a link to more info on his optra but from what he is saying it sounds like the u20sed wouldnt be a good swap idea if you plan to boost because after 200ft lbs the tranny breaks....this also mean that the aveo's tranny will probably brake under less torque than that since it is rated lower than that. since its D16 (or F16 i forget which) itll probabyl only hold til 160 ft lbs
